Edit Control - Get Line Cursor

Recommended Posts

Cythor

Hello people.
I need the Line Number of the Cursor in a Edit Control.
But I haven't a idea how I can do that.

I need a idea or a beginning for my problem.

I hope you can help me.

Cythor =)

Cythor,

This should give you the idea: ;)

#include <GUIConstantsEx.au3>
#include <EditConstants.au3>
#include <GuiEdit.au3>

Global $aLocation[2] = [0, 0]

$sText = "This is a long pice of text which should require wrapping in the edit control - " & _
        "which is provided by the combination of $ES_WANTRETURN and $ES_MULTILINE styles"

$hGUI = GUICreate("Test", 500, 500)

$cEdit = GUICtrlCreateEdit($sText, 10, 10, 200, 200, BitOR($ES_WANTRETURN, $ES_MULTILINE))

$cButton_Locate = GUICtrlCreateButton("Locate", 10, 300, 80, 30)
$cButton_Reset = GUICtrlCreateButton("Reset", 10, 350, 80, 30)
$cButton_Relocate = GUICtrlCreateButton("Relocate", 10, 400, 80, 30)

$cLabel_Line = GUICtrlCreateLabel("Line: ", 100, 300, 100, 20)
$cLabel_Col = GUICtrlCreateLabel("Col: ", 200, 300, 100, 20)

GUISetState()

; Set cursor to start
_GUICtrlEdit_SetSel($cEdit, 0, 0)

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cButton_Locate
            ; Show and save current position
            GUICtrlSetData($cLabel_Line, "Line: " & ControlCommand($hGUI, "", $cEdit, "GetCurrentLine", ""))
            GUICtrlSetData($cLabel_Col, "Col: " & ControlCommand($hGUI, "", $cEdit, "GetCurrentCol", ""))
            ; Get current position in usable form
            $aLocation = _GUICtrlEdit_GetSel($cEdit)
            GUICtrlSetState($cEdit, $GUI_FOCUS)
        Case $cButton_Reset
            ; Reset cursor to start
            GUICtrlSetState($cEdit, $GUI_FOCUS)
            _GUICtrlEdit_SetSel($cEdit, 0, 0)
        Case $cButton_Relocate
            ; Relocate cursor to stored position
            GUICtrlSetState($cEdit, $GUI_FOCUS)
            _GUICtrlEdit_SetSel($cEdit, $aLocation[0], $aLocation[1])
    EndSwitch

WEnd
Please ask if you have any questions? :)

Thank you very much for the code.

I will write the Line Numbers left of the Edit Control.

But the GUI is to little for long texts.

The rest can I do alone.

If the edit has scroll bars for longer text then writing the line numbers to the left will require that you write the line numbers in another edit and synchronise the scrolling. I did an example for that somewhere so if you need that I will try to find it, otherwise I am happy to do nothing.
